R3D® - IND

Application

﻿The Rochester Remote Ready Dial, R3D®, is a magnetically-driven, Hall Effect compatible dial. Dials are utilized on stationary applications where direct reading plus an electrical signal to a remote fuel level monitor may be required. Models are available to fit all Rochester Junior and Senior liquid-level gauges.

Rochester’s Hall Effect Module is designed to snap-fit into the recess in the Remote Ready Dial lens. Once installed, the module can provide ratiometric voltage output proportional to the liquid volume inside the tank.

General Information & Features

﻿In the area of fuels, lubricants and many other liquid measurements, a magnetic drive feature is important because a magnetic drive allows a signal from the float mechanism inside the tank to be transmitted through a solid bulkhead.

The R3D® - IND dial is designed to allow a second magnetic coupling. This is a coupling from the R3D® - IND pointer magnet, through the sealed lens and into the Hall Effect Module.

Previous designs of magnetically driven dials that produce an electrical output signal had the disadvantages inherent in using variable resistors with a wiper arm contact. The magnetic connection of the Hall Effect sensor is more reliable than systems that depend on the sliding contact of variable resistor devices.

Hall effect is a solid state technology with no moving contacts. It counts on the fact that a magnet bends the path of electrons moving through a semiconductor. The bending of the electron path can be detected and converted into an electrical signal.

The R3D® - IND and Hall Effect Module can be used as a retrofit on existing tank gauges to provide an electrical output which can be utilized for remote monitoring of tank levels. Existing tank gauges without ad R3D® dial can be retrofitted using 5ACRS02898 (Sr.) or 5ACPS02898 (Jr.) dials. Remote monitoring of tank levels provides another source of level gauging in addition to manually checking dial gradients.

The R3D® - IND case is hermetically sealed by ultrasonic welding to melt and fuse the case into one solid piece. This keeps weather out, ensuring “no-fog” readability while greatly extending mechanical life. The seal is a high reliability, no-gasket design.

The plastic case is far more resistant to corrosion than any metal-cased version and is capable of withstanding broad variations in temperature. The lens and case are a spe­cial, UV stabilized plastic material.
